A Le Mans Prototype (LMP) is a type of sports prototype race car used in various races and championships, including the 24 Hours of Le Mans, FIA World Endurance Championship, IMSA SportsCar Championship, European Le Mans Series and Asian Le Mans Series. Le Mans Prototypes were created by the Automobile Club de l'Ouest (ACO). The technical requirements for an LMP include bodywork covering all mechanical elements of the car. As of 2023, there are two classes within Le Mans Prototypes, designated LMP2 and LMP3.
The All Japan Sports Prototype Championship (全日本スポーツプロトタイプ選手権), abbreviated as JSPC, formed by the Japan Automobile Federation, was a domestic championship which took place in Japan for Group C and IMSA GTP prototype cars and also featured cars that were eligible for touring car racing in its earlier years. Class A and Class B for production cars which were defined by the FIA and the lead category, Class C would be for cars that are similar to IMSA's Camel Lights and the WEC's C2, whereas Class D was for C1/GTP cars.
The Nissan R90C was a platform used for Group C racing cars built in 1990 by Nissan Motors for competition in World Sportscar Championship (WSC) based in Europe and the All Japan Sports Prototype Championship (JSPC). The cars based on the basic R90C platform would compete until 1993 before Nissan chose to withdraw from sports car racing, not returning until 1997. It won three JSPC championships and several significant endurance races during its career.
The Nissan P35 was a planned Group C car built by Nissan Motors for competition in the World Sportscar Championship. Developed by Nissan Performance Technology Inc. (NPTI), which had formerly raced under the name Electramotive in the United States, the cars were intended to be completed by the middle of 1992, with competition starting in 1993. However economic troubles for Nissan led to the cancellation of the project soon after testing of the first cars had begun, meaning that the P35s never raced.
Richard Lloyd Racing (RLR), originally named GTi Engineering, was a British auto racing team created in 1977 by driver Richard Lloyd. Originally named for the Volkswagen Golf GTIs that Lloyd raced in the British Saloon Car Championship (BSCC), they went on to become a successful Porsche privateer in the World Sportscar Championship (WSC). Richard Lloyd Racing eventually folded at the end of the 1990 season due to the increased cost of the World Championship.
The 6 Hours of Fuji is a sports car race held at Fuji Speedway in Oyama, Shizuoka, Japan. The race was held for the first time in 1967, and in 1977 became part of the new Fuji Long Distance Series. In 1982 a second 1000 km race known as WEC in Japan was run as a round of the World Sportscar Championship. The All Japan Sports Prototype Championship was formed in 1983, and since then co-sanctioned this event. The World Championship left after 1988, but the JSPC carried on both races until 1992. The race was revived in 1999 as an attempt to gauge interest in an Asian Le Mans Series; the series never materialized. The race was revived again as a part of the short-lived Japan Le Mans Challenge in 2007. The race returned again as part of the 2012 FIA World Endurance Championship season, but changed to a 6-hour race, with no distance limit.
